Geomagnetic storm - Wikipedia
A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave.
Geomagnetic Storms - NOAA / NWS Space Weather Prediction …
A geomagnetic storm is a major disturbance of Earth's magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth. These storms result from variations in the solar wind that produces major changes in the currents, plasmas, and fields in Earth’s magnetosphere.

CME Arrival at Earth has Occurred and Warnings have been Issued
2024年10月12日 · The anticipated coronal mass ejection (CME) arrived at Earth at 11:15am EDT at nearly 1.5 million miles per hour. The CME strength and structure are being closely scrutinized for potential geomagnetic storm intensity, but, G3 levels are now expected due to the magnitude and potential of the CME, therefore G3 or greater warning has been issued.
